Be it known that I, GEORGE L. So orIELn, a citizen of the United States, residing at Kansas-City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Clamps for Spoke-Wheels; and I do declare the following to be a full, clear, and exact description of the invention, such as willenableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,andto the, letters and figures of reference marked thereon, which form a part of this speclfication.

This invention relates to clamps for spoke wheels andparticularly to a clamp adapted to carry a sprocket, a gear or the like, from which power may be communicated to a driven element.

This application is a division of an-appli cationfiled by me on or about July 1,1918,

Serial No. 242,911, which matured into Patent No. 1,356,475, October 19, 1920.

Motor vehicles are being employed in connection with work other than that for which they were originally intended, as for example,- as thepower medium of tractors, as power for driving saw mills and for other purposes, and I have provided means whereby a clamp may be applied to the rear wheel of a'n otor vehicle as an auxiliary element, so that the clamp may be useful in applying the power of the driving, axle to some useful purpose other than propelling a motor vehicle. 1

' Vvhere the motor vehicle is used as the driving power for a tractor, means must be provided for transmitting the power from the motor vehicle to the driven part of the tractor; and a convenient means of doing this is through sprockets and chain.

I have provided a clamp to which a sprocket or gear may besecured, the clamp" being readily adjusted to and easily re moved from the spokes of a wheel. I have also provided means whereby the sprocket or gear may be placed in alinement with a driven elementon the tractor irrespective of variations in the tread of the motor vehicle used as the driving power.

The clamp is shown asconsisting of a 51161111 015 frusto conical form and provided at the base of the cone with an outwardly disposed circumferential flange 2, provided on its face with a plurality ofv spoke engagingseats 3 which may be formed in- Between the seats. 3 areopenings 1 for the reception of fastening devices whereby the seats may be caused to bind against the spokes to secure the clamp in. place. H i The fastening devices are best shown in Fig. V" as consisting ofshackles 5 substantially U shap'ed, the legs 6 and 7 beingpref- 'erably threaded to receive the nuts 8 and 9,

after the legs 6 and 7 have passed through the openings 4:. l

At the frustum of the cone is an inwardly extending flange 10 provided with a plurality of openings 11 toreceive the fastening devices 12 which are shown as bolts whereby the sprockets 13 may be securedto the clamp, said sprockets being readily removable by loosening the nuts 14 so the different sprockets orgears may be readily 3 WVhile Ihave shown a sprocket attached to the clamp, it is obvious that other devices projectingthrough the openings 4, where,

upon the securing nuts 8 and 9 may be applied in obvious manner.

Ordinarily the tread of motor vehicles is I standardized at 56V inches, some motor vehicles however, have treads-of 54 inches and ,might be applied, as forexample a gear of most of the driven sprockets for tractors are arranged for 56 inch. If a motor vehicle with a lesser tread is employed, the sprocket 13 and the sprocket which it drives, would not be in alinement so in order to provide for the discrepancy I have shown supple mental seats 16 in rig. IV which may be placed against the flange 2 between the seats 3 and these seats 16 are provided at their ends with notches l7 and lSadaptedto he:

tread, the introduction of the supplemental seats will compensate for the discrepancy and the sprockets on the clamp will come into alinement with those on the tractor.

lVhen it is desired to use the motor vehicle as a pleasure car, the clamp may be readily removed by releasing the shackles 5.

Having thus describedm invention what I claim as'new therein, an desire to secure binding theseats and spokestogethen- 2. A sprocket supporting member, removable spoke engaging seats at one end of said member and fastening devices engaging the spokes of the wheel to which the device is attached, 7 said fastening devices passing through the said member engaging the seats to hold them in place. i a

3.A device of the class described comprising a frusto conical shell, an inwardly approaching flange on the frustum of the shell, and an outwardly projecting flange on the base of the cone and spoke engaging seats on the last mentioned flange.
